I applied through a staffing agency. The process took 5 days. I interviewed at Serco Group (Newcastle upon Tyne, England) in Nov 2015
Interview
Simple group meeting, sat down, informal chat. Did some simple team tasks and activities. The average "Show how you work in a room of new people" listening test type things.
Second stage was a slightly more formal one on one interview, questions could be pretty easily answered with some basic industry knowledge.
I applied through a staffing agency. The process took 1 week. I interviewed at Serco Group (Newcastle upon Tyne, England) in Jul 2016
Interview
I was contacted by a recruitment agency and put forward for interview the following week. After an initial presentation on the job role and Serco, all candidates individually completed a competency based exercise online. During this candidates would be called into their one on one interview and phone based role-play exercise. The process took between 2-3 hours. The interviewers were friendly and informative, though the process was slightly disorganised and resulted in some waiting around.
